11 Claims.

its object is to provide a magazine for holding such lms and a fingeractuated mechanism for permitting them to drop one at a time intoalinement with a light orifice and a lens and to provide anotherarrangement for permitting their removal from the device. Another objectis to provide a device for feeding mounted films through a projector.

. These and other objects will appear in the following specication inwhich I will describe an embodiment of the invention, the novel featuresof which will be set forth in claims.

Referring to the drawings:

Figure 1 is a sectional side elevation of a film viewer which isjmadeaccording to and embodies my invention.

*y Figure 2 is a front elevation in Figure 1; n

Figure 3 is a top plan View of the device shown in the preceding gures;

Fig. 'si is a perspective view of amounted film.

IU is a hollow outer casing which is open at the bottom. The innersurface I of its front wall I2 forms the front wall of a magazine. Alight opening I3 is cut through the lower partr of the wall I2 and isclosedl by a translucent film or plate I4. The central lower part of thewall I2 is cut away, as shown atl I5. Lugs or ears I6 having upwardlyinclined inner surfaces extending inwardly from the lower corners of thefront wall.

of the device shown Side walls and I8 extend inwardly from the l frontwall throughout its length. Theparts of their inner surfaces adjacentthe front wall are flat and at right angles to the surface II.

20 is a top wall which has a front edge 2| parallel to and spaced fromthe surface It is provided with a vbore 22 through which a button 45projects. A rear wall 23, which is integrally connected with the topwall and the side walls, extends downwardly at an angle from the surfaceII. It is provided with a shouldered orice24, symmetrically disposed inrelation to the light opening I3 for the reception of a magnifying Vlens25 which is held in place by a split ring'26. 2l is a lugwhich projectsinwardly from the central part of the lower edge of the rear wall. Thelower surface of this lug, the lower edge of the rear wall,and the loweredges of the side walls are in a plane atrightangles to the surface Iand above the'earsII.v Y e' f 30 designates lari-inner member whichcomprises 2 a base 3| which has a flat upper surface from the frontcorner of which ears 32 extend. Its flat surface fits against the loweredges of the rear and side walls and the lug 2l and its ears 32 arebeveled to fit the ears I3 at the lower corners of the front wall. Fromthe forward edge of the base 3| a frame 33 extends upwardly. This frameis cut out, as at 34, to a size substantially corresponding to that ofthe light opening I3. Its front surface 35 is slightly concave inrelation to the surface I I of the outer casing. A shelf 36 extendsinwardly from the upper end of the frame 33. 31 designates a flathorizontal slot formed in the base 3| with its upper surfacesubstantially parallelwith the fiat upper surface of the base.

The central part of the base is cut away, as shown 40 is a bell cranklever pivoted to the shelf 36 at 4I. At the end of its longer arm is atransverse bar 42. Its shorter arm is pivoted at 43 to a rod 44 whichextends from the bottom 45. A shoulder 46 is formed at the lower end ofthe bottom against which a spring 4l, seated on the shelf 36, presses.

A flat slide 50 is guided in the slot '31. This is pressed against thesurface I by a spring 5|. 52 is a pin afiixed to the slide 50 extendinginto the space formed by the cut away portion`38 of the base 3|.

When the parts are assembled, the earsv32at the. front corners of thebase 3| engage the lugs I6 at the lower corner of the front wall. Theinner member is then secured to the outer casing by a screw 28 whichpasses through the base 3| into the lug 21.

Adesignates a mounted film such as a transparent colored positive. Arectangular opening 29 is formed in the top of the device between theedge 2| of the top and the rear surface II of the front Wall and betweenthe sides I1 and I8. This opening, in the particular case illustrated,is proportioned to admit fifteen of these films into the magazine orspace above the shelf 35.

A slot 39 is formed between the surface I and the upper forward edge ofthe frame 33 of a width slightly greater than the thickness of one ofthe mounted films but less than the thickness of two of them. One of thelms may pass through this slot onto the slide 50, into the position inwhich it is shown at A in Fig. 1. It will then be in registration withthe light opening I3 and can be seen through the magnifying lens 25.When it is desired'to remove this ihn, the slide 50' is pushed back fromunder it by the engagement of the operators linger on lthe pin 52. Y i fIn Fig. 1 four other iilms are shown at A2, one of which is above and inalinement with the aforesaid slot 39 and three of which rest upon theshelf 36. The bar 42 engages the lm at the rear with suiiicient pressurecaused by the spring 41 to keep these lms in the position shown. Whenthe button 45 is depressed, the bar 42 is swung back toward the positionin which it is shown at 42A so that pressuiie-onfthe films is iremoved;The lm over thecslot 31-ewi11-3then drop.- down intothe position A inthe film guide formed between the surfaces I l and 35. This operationmay be re.-

peated until all of the films inthemagazne, have been passed through thedevice.

Various modifications in construction, mode 4of operation, method anduse of anfnuention 'may Y and do occur to others, especiallyafterberief. fitting from knowledge of such disclosure as that hereinpresented of the principles involuednrbutf the invention itself is notconfined to the present Showing,
